Original Abstract

The necessity of continuously saving of natural resources and the continuously increasing utilization of waste materials, which results in by product of the primary production, is in the interest of sustainable life on the Earth. These valuable secondary raw materials are stored as waste and urge for use as inexpensive and easily available material. The Institute of Building Materials and Elements Technology at the Brno University of Technology, solves in the long term the problem of alpha gypsum preparation by dehydrating the gypsum in the solution of chloride salts. The gypsum dehydrates to alpha-hemi-hydrate by this method under atmospheric pressure in liquid environment. The tests were brought as far as to the stage of laboratory production. The chloride ions are after dehydration washed out and afterwards the gypsum is dried.
